According to a recent study, Korean teenagers aged between 15 and 19 send an average of 60.1 text messages a day. That works out to nearly 2000 text messages a month. What's more, the trend appears to be increasing, because when they got information about 2005, the average was just 59.5 messages per day. Young adults aged between 20 and 24 are less inclined to send text messages, but they still send quite a few, average 30.9 per day (22.6/day in 2005).

Text messaging has become such a rampant problem in Korea that "it's not uncommon for people to develop carpal tunnel" syndrome.
